STEEL-WOOL-PAD HOLDER.

Application filed January 20, 1928. Serial No. 2 18218.

' My invention relates to steel wool holders.

It is the object of my invention to provide a steel wool holder on which a steel wool pad may be quickly mounted and which will be retained on the holder despite the uses to which the steel wool is put.

These cup-shaped pads are customarily subjected to considerable strain in that the holder is held atan angle to theobjectbeing treated by the wool so that the princi a1 pressure and abrasive force comes on the e ge of the pad which serves to loosen it from the holder and tear it apart.

My invention provides a simple means of positively causing the wool pad to adhere to and be attached to the holder and to resist this particular strain.-

It is a further object of my invention to so arrange the pad on the holder that, by the rotation of the pad, the strands of the wool composing the pad will be drawn more tightly and closely about the upper surface of the tapered head of the holder thereby making it nearly impossible to pull the pad off the holder. Counter rotation to release this tension due to the winding of the threads of wool is prevented by the shoulders.

Referring to the drawin s:

Figure 1 is a side elevation of the holder;

Figure 2 is a; bottom plan view;

Figure 3 is a section on the line 3-3 showing the holder with the wool pad in position;

Figure 4 is a side elevation of the holder with the pad in position;

Figure 5 is a side elevation of the holder with the pad after the pad has been rotated and its upper end has been drawn inwardly due to the rotation of the ad and winding of the threads on the tapere head;

Figure 6 is a section taken vertically through the pad showing the denser arrangement of the threads as-a result of the winding and the rotation of the pad on the holder;

Figure 7 is a section on the line 77 of Figure 6; a

Figure 8 is a side elevation of a modified form of handle; v

Figure 9 is a bottom plan view thereof; Figure 10 is a section on the line 10- -10 of Figure 9;

Figure 11 is a Figure 10.

Referring to the drawings in detail, 1 is a handle having an annular projecting shoulder near the bottom thereof designated 2.

section on the line 11-11 of Below this annular shoulder and spaced inwardly therefrom is an outwardly and downwardly tapering head 3 having a flat bottom 4. This tapering head terminates in a sharp edge 5 which is provided with a plurality of notches 6. These notches are formed by a radiallyvertical wall 7 and a downwardly and inwardly sloping wall 8 at right angles to the wall 7, thus providing a notch which converges outwardly and upwardly forming a triangular spaced opening with the basc of the triangle in the plane of the base 4 of the holder.

The wall of the pad 9 being cup-shaped and of somewhat lesser diameter than the diameter of the head 3 where the diameter is taken from edge to edge 5 is forced over the enlarged outwardly extended head 3 so that the. bottom 4 of the head fits within the bottom of the steel wool cup and the resilient nature of the cup causes the walls of the cup to engage with the side walls 3 of the head and the upper edges of the cup to engage with 'the underside of the annular shoulder 2.

The operator then grasps the handle with one hand and the steel wool pad with the other causing the pad to rotate on the handle in a direction which will force the' wool against the vertical faces 7. The Wool will be caused to enter the wedge-shaped opening or notch so that the greater the pressure on the edge of the wool as it is rubbed alon the surface which it is treating the more fiimly the wool will be forced into the retaining notch.

10 indicates the threads of wool which have been wound more tightly upon the tapered surface of the head 3 above the outwardly flarim edge 5.

In igures 8 to 11 inclusive, there is shown a form of handle in which the groove formed in the other forms by the tapered head is made with a bottom 11 parallel to the main axis of the handle so that the overhanging shoulder 2 forms one wall of the groove while the right angle inner wall 12 of the tapered head 3 forms the other wall of the groove so that the strands of wool can be wound more completely between these shoulders in this roove. A series of hooks or notches is ormed in the head-3 consisting of the cutaway portions 13 adjacent the shoulders 14 which are directed slightly oil the radius line to form a hook. They may, however, be direetly on the radius line if desired. The wall 15 of the notch tapers downwardly and inwardly. v Thus, the user of the pad may rotate the pad in one direction inorder to get the pad rotate tightening the strands thereof in the groove 1.1.

' It will be noted that the upper outside por tion of the wall of the steel wool pad tapers inwardly by reason of this winding movement which draws inore tightly inwardly the loose steel wool strands which are wound into the pad.

It will be understood that I desire to comprehend within my invention such modifications as may be necessary to adapt it to varying conditions and uses within the scope of the claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a steel wool holder, a handle, having' a base supporting a mass of wool adapted to permit the mass of wool to rotate thereon, said base having retaining notches so inwardly disposed that upon a rotation of the wool, portions of the Wool will be forced into said notches for retaining the wool on the base.

2. In a steel wool holder, a handle, having a base supporting a mass of wool adapted to permit the mass of wool to rotate thereon, said base having retaining notches so inwardly disposed that upon a rotation of the wool, portions of the Wool will be forced into said notches for retaining the wool on the base, said base being tapered inwardly and upwardly.

3. In a steel wool holder, a handle, having a base supporting a mass of wool adapted to permit the mass of wool to rotate thereon, said base having retaining notches so inwardly disposed that upon a rotation of the wool, portions of the wool will be forced into said notches for retaining the wool on, the base,said base being tapered inwardly and upwardly, an abutting shoulder above said head iorlimiting the upward movement of the holder on the wool.

4-. In a steel wool holder, the combination of a handle, an annular shoulder spaced from one end, a wool supporting head having outwardly flaring side walls, said head having a series of peripheral notches adjacent the outer edge thereof, said notches having one wall arranged in line with the radius of the head and the other wall arranged in a plane at right angles to the first mentioned wall but tilted with respect to the horizontal so that the second wall is arranged downwardly and ikpwardly on a tangent to the periphery of the ead.

In testimony whereof, I afiix'my signature.
